Though citizens and second generation residents in many cases, American Muslims face a combination of suspicion, government scrutiny, and social segregation in the United States, despite significant education and economic assimilation in America. The crux of the investigation advanced here centres on how group influence, emotions, and religious interpretation contribute to the political orientation and behaviour of a national sample of Muslims living in the American context. A compelling explanation as to how members of an ostracized political group marshal the motivation to push through suspicion to become fully engaged political actors, this book has wide relevance and will be of interest to scholars researching Muslims and political participation across the fields of political science, history, sociology, and religion.
